Hi all,
can someone help me out "quickly"? I would like to calculate for any given position XYZWPR whether it is singular or not. I already know it can be done with the determinant. If the determinant is not equal to 0, then the linear system of equations can be solved (and the according matrix can be inverted). If the determinant is equal to 0, then the columns (or rows) are linearly dependent, i.e. the position is singular.
I'm just a bit lost with the application. My problem is: how do I convert a position into its matrix in order to calculate the determinant?
Incidentally, I'm not just interested in the pure application, but in understanding what happens under the hood.
Thanks for any enlightenment.
